TRN Verification UAE: How to Check Any Tax Registration Number (2026)

What Is a TRN (Tax Registration Number) in the UAE?

A TRN (Tax Registration Number) is a unique 15-digit identifier issued by the Federal Tax Authority (FTA) to every business that registers for VAT in the UAE. If your annual taxable supplies exceed AED 375,000, VAT registration — and therefore a TRN — is mandatory. Voluntary registration is available from AED 187,500.

The TRN format is: 100-XXXXXXXXXX-XXXXX (15 digits, starting with 1).

Knowing how to do TRN verification UAE is essential before you pay any supplier invoice, sign a contract, or reclaim VAT input tax credits. Unverified TRNs cost UAE businesses millions in invalid VAT reclaims every year.

Why You Must Verify a Supplier’s TRN Before Paying

Under UAE VAT law (Federal Decree-Law No. 8 of 2017), you can only reclaim input VAT if the supplier issuing the invoice is a legitimately registered VAT taxpayer. If you pay VAT on an invoice from a company with a fake or expired TRN, the FTA will:

• Disallow your input VAT claim
• Issue a penalty of AED 10,000–50,000 for knowingly accepting invalid tax invoices
• Flag your business for a VAT audit

Always verify TRN before processing supplier payments, especially for first-time vendors and freelancers.

How to Verify a TRN in the UAE — Step-by-Step (FTA Portal)

The FTA provides a free, official TRN verification tool. Here’s exactly how to use it:

1. Go to the FTA VAT verification portal: Visit vatverification.tax.gov.ae
2. Enter the TRN: Type the 15-digit TRN number exactly as shown on the invoice (no spaces or dashes needed in most cases)
3. Enter the security CAPTCHA: Complete the image or text captcha displayed on screen
4. Click “Search”: The system queries the FTA’s live business registration database
5. Review the result: A valid TRN returns the registered business name and registration date. An invalid TRN returns “No results found”
6. Cross-check the name: Confirm the registered name matches the name on the invoice. If they differ, contact the supplier before paying

Pro tip: Bookmark vatverification.tax.gov.ae — your accounts team should run this check for every new supplier automatically.

What a UAE TRN Looks Like (Format Guide)

A legitimate UAE Tax Registration Number always follows this format:

Feature	Details
Total digits	15
Starting digits	Always starts with 1
Example format	100XXXXXXXXXXXX (e.g., 100312345678910)
Issued by	Federal Tax Authority (FTA), UAE
Used for	VAT invoices, tax returns, input tax claims
Displayed on	All VAT tax invoices (mandatory by law)

If you receive an invoice where the TRN has fewer or more than 15 digits, or doesn’t start with 1 — it’s invalid. Do not pay until you receive a corrected invoice.

What to Do When a TRN Is Invalid

If the check TRN UAE portal returns no results, take these steps immediately:

1. Do not pay the VAT portion of the invoice until verified
2. Contact the supplier and request their official FTA registration certificate
3. Ask them to check their own TRN — sometimes businesses forget to renew their VAT registration or have a typo in their documentation
4. If they can’t provide valid proof: Pay only the base amount (ex-VAT) and raise an amended invoice
5. Report suspected fraud: If you believe the TRN is deliberately fake, report it to the FTA via tax.gov.ae

TRN vs Business Registration Number — What’s the Difference?

Feature	TRN (Tax Registration Number)	Business Registration Number
Issued by	FTA (Federal Tax Authority)	DED / Free Zone Authority
Purpose	VAT registration and tax invoicing	Legal entity identity / trade license
Format	15 digits starting with 1	Varies by emirate / free zone
Required for	Charging VAT, reclaiming input tax	Operating legally in UAE
Mandatory if…	Annual taxable supplies > AED 375,000	Always — for any UAE business
Can be verified	vatverification.tax.gov.ae	DED portal or free zone website

Many UAE businesses confuse these two numbers. Your trade license number is issued when you form your company. Your TRN is issued only after you separately register for VAT with the FTA.

Do You Need a TRN for Your Business?

If your business annual taxable turnover in the UAE exceeds AED 375,000, VAT registration and a TRN are mandatory. Below this threshold, registration is optional (but recommended if you want to reclaim input VAT on purchases).
